Abstract: DEVICE OR TRANSFERRING A FIBER WEB            ABSTRACT OF THE DISCLOSURE          A device for transferring a paper web from the press section into the dry end of a paper making machine.          The web contacts a rotatable press surface, e.g. on a press roll, and travels with the press surface through a press nip against a backing roll, and thereafter travels with the press surface to a web removal place.  The web is transferred by a suction device across an adjustable gap to a porous transport belt which transports the web toward a first dryer group.  The first dryer group has a number of drying cylinders and a web support belt that transfers the web from drying cylinder to drying cylinder.  Either a suction device or another intermediate transfer roll transfers the web from the transport belt to the support belt of the dryer group.          An adjustable speed control device operates the drive to the press surface, the drive to the transport belt and the drive to the first group of drying cylinders and their respective support belt so that there is a positive difference in speed between the web at the press nip and the speed of the web at the transport belt with the web moving faster at the transport belt and a positive difference in speed between the speed of the transport belt and the speed of the web support belt with the web moving faster on the support belt.

Title: Method for analyte classification by sc profiles
Inventor: KAUVAR LAWRENCE M
IPC: G01N33/543
Filed: 1992-04-02
Abstract: The precision of identification of analyte composition in a sample, where the possible analytes each provide a series of va-lues for characteristic parameters; in particular where the parameters are generated by cross-reaction with specific binding rea-gents, is enhanced by applying pattern recognition techniques. Samples to be tested are evaluated with respect to each survey par-ameter to obtain a pattern of parameter values with respect to each analyte at a given concentration. In the case of the use of a panel of specific binding reagents, the samples to be tested are reacted with this panel and the affinities at various analyte concen-trations are determined. This results in a databank of "SC profiles" for known concentrations of each analyte. This databank is stored in a computationally accessible form, which then can be matched against SC profiles obtained by testing unknown sam-ples.
Patent CA-2108103-A1 (CA)
Inventor: FATTOUCHE MICHEL
IPC: H03H17/02
Filed: 1993-10-08
Abstract: A signal that may be represented by a band limited periodic function m(t) is transformed into its z-domain zeros using characteristics of the signal in the neighbourhood of fades of the signal, namely a bounds of the fades and the depths of the fades. The z-domain zeros are the zeros of the function in the complex plane, and represent local minimums of the function. The z-domain zeros are used to estimate the discrete spectrum of m(t), and the differential phase of m(t) is derived from the envelope of m(t) using the concept of the z-domain zeros. Also, speech is compressed based on the z-domain zeros of a signal m(t) that represents a speech signal, and knowledge of the location of fades is used in interference reduction at single moving antennas by applying a spectral resolution technique during a fade and applying notch filters to the signal to resolve the signal components.

Title: Amino acid derivative and bromoacetyl modified peptides
Inventor: INMAN JOHN K
IPC: A61K47/48
Filed: 1992-06-10
Abstract: A new amino acid derivative, N.alpha.-tert-butoxycarbonyl-N.epsilon.-(N-bromoacetyl-.beta.-alanyl)-L-lysine (BBAL), has been synthes-ized as a reagent to be used in solid-phase peptide synthesis for introducing a side-chain bromoacetyl group at any desired posi-tion in a peptide sequence.  The bromoacetyl group subsequently serves as a sulfhydryl-selective cross-liking function for the pre-paration of cyclic peptides, peptide conjugates and polymers. BBAL residues are stable to final HF deprotection/cleavage. BBAL peptides can be directly coupled to other molecules or surfaces which possess free sulfhydryl groups by forming stable thi-oether linkages. Peptides containing both BBAL and cysteine residues can be self-coupled to produce either cyclic molecules or linear peptide polymers.  Such peptide derivatives are useful in preparing potential peptide immunogens, vaccines and therapeu-tics, and for substances such as peptides linked to polymers, plastics, enamels and ceramics.

Title: Curl Spring Shoe Based Window Balance System
Inventor: WESTFALL NORMAN R
IPC: E05F1/16
Filed: 1994-03-21
Abstract: A window balance system for a tilt sash uses a pair of constant force curl springs having curled convolutions carried by sash shoes and free end regions mounted in sash shoe channels above the region of travel of the shoes.  The recurl tendency of the springs imparts a lift to the curled spring convolutions, and the shoes transmit the lift to the sash.  The springs recurl into the convolutions as the shoes rise and uncurl from the shoes into the shoe channels when the shoes move downward, and neither movement requires the springs to slide frictionally within the shoe channels.  Each shoe is preferably formed of two identical halves that are assembled to trap the curl spring along with a cam that locks the shoe when the sash tilts.
